Technical characteristics

Heat-resisting nickel alloy HN62MWKJU is intended for manufacturing turbine blades that are exploited at a temperature of not higher than 900 °C. The main requirements are conditioned by the latest developments of engine constructions, continuous increasing of plasticity, resistance to low-cycle and thermal fatigue, heat resistance, resistance to an effect of gas environment. Material of modern engines for turbine blades must possess a high resistance to breakage at thermal and low-cycle fatigues which are the main types of breakage. A risk of breakage can increase by surface reactions. They appear because of grain boundary softening and gas corrosion.

Type

Description

limitedly weldable

welding is possible at heating to 100−120°С and last heat treating

hardly weldable

in order to obtain a qualitative welded joints, it is necessary to perform the following operations: while welding to heat it up to 200−300°C, to do a heat treating (annealing) after welding

weldablewithout stint

welding is done without further heat treating or previous heating
